我创建了一个包含一些数据的数组缓冲区:
var myArray = new ArrayBuffer(512);
var longInt8View = new Uint8Array(myArray);
for (var i = 0; i < longInt8View.length; i++) {
longInt8View[i] = i % 255;
}
我把它通过POST发送给服务器:
if (window.XMLHttpRequest) {
var xmlhttp = new XMLHttpRequest();
} else {
var xmlhttp = new
这是一个十进制到二进制转换器。我需要帮助解释背后的数学是因为我不知道如何解释所有的轮班等。
number = int(raw_input("Enter the Number:"))
binary = ''
while number > 0:
binary = str(number % 2) + binary
number >>=1
print(binary)
这是AJAX代码:(在这个简单的例子中,“newContent”是“尝试连接”)
$.ajax({
type: "POST", //i have tried method: "POST" but still not working
url: "change.php",
data: {"edit": newContent},
success: function(response){
console.log(response);
}
我很困惑。考虑一下这段代码按照我所期望的方式工作:
>>> foo = u'Émilie and Juañ are turncoats.'
>>> bar = "foo is %s" % foo
>>> bar
u'foo is \xc3\x89milie and Jua\xc3\xb1 are turncoats.'
这段代码完全不是我所期望的那样工作:
>>> try:
... raise Exception(foo)
... except Exception a
以下是我的代码:
QFile f("tql.dll"); //a file to be copied
f.open(QFile::ReadOnly);
QByteArray qba = f.readAll();
f.close();
QString hexstr = qba.toHex();
qba = QByteArray::fromHex(hexstr.toLatin1()); //i try this and it dose not change the original data
QFile f2("tql3.dll");
f2.open(QIODevi
我有以下PHP代码:
$tagId = 1; // the original value of tag
$tagIdAsHex = sprintf("%02X", $tagId); // the tag value in hex format
$tagAsHexBytes = pack('H*', $tagIdAsHex); // the packed hex value of tag packed into string as a conversion
我如何把它翻译成C++呢?
byte tagId = 1;
auto hexedTag =

我试图使用PHP从字节字符串构造JPEG图像。我理解base64解码和编码部分,但现在我的部分数据如下所示:
